Abstract

"MéTODO E APARELHO PARA CODIFICAR BLOCOS INTRA-INTER CODIFICADOS HìBRIDOS". Trata-se de um modo de codificação com prognóstico duplo (ou com múltiplos prognósticos) intra-inter híbrido que permite ambos prognósticos intra quadro (intra) (301 na FIG. 5) e inter quadro (inter) (302 na FIG. 5) serem combinados para a codificação híbrida de um macrobloco ou de um sub-bloco corrente (310 na FIG. 5). O prognóstico duplo pode ser utilizado também em imagens I, combinando dois prognósticos intra que utilizam duas direções de prognóstico intra diferentes. Um codificador de vídeo (700) processa dados representando uma imagem de vídeo bidimensional que foi produzida por uma câmara de vídeo convencional comercialmente disponível. O codificador de vídeo é adaptado para selecionar codificar uma macrobloco corrente entre um modo de codificação intra, um modo de codificação inter de quadro P, um modo inter com prognóstico duplo de quadro B e um modo de codificação com prognóstico duplo intra-inter híbrido. Um decodificador de vídeo (800) recebe e decodifica um fluxo de dados que pode conter um bloco / macrobloco codificado de acordo com o modo de codificação com prognóstico duplo intra-inter híbrido.
